How do u get to that stage without calmag ? Do u use tap water or ro ?

Noticed the leaves colour faded so it was the pH of the soil a bit too low, plant was not drinking also as much so just increased the pH on the next feeding just 0.5L with a bit of extra nutes on ratio 1-4-3 after 2 days is back on the green side and blloom also jumped off to bigger and thicker buds but still a bit more to go

So the pot is about 12 L and not 1.5 L
